ARTIFICIALFOOT.

SPECIFICATION forming part of Letters Patent No. 726,889, dated May 5, 1903.

Application filed August 1a, 1902. T

of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and usefulflmprovements in Artifi-- cial Feet; and I do hereby declare that the following is a full, clear, and exact description thereof. 1

My invention has for its object to provide simple economical artificial feet that when in use will simulate the action of natural feet and take up the jar that renders ordinaryartificial feet objectionable, said invention consisting in what is hereinafter particularly set 4 I claim as new, and desire to secure by Letters forth with reference to the accompanying drawings and subsequently claimed.

Figure 1 of the drawings represents a con tral longitudinal sectional view of an im-'- proved artificial foot in accordance with my invention, and Fig. 2 a transverse section of the same indicated by line 2 2 in the first figure.

Referring by letter to the drawings, the artificial foot herein shown consists of a layer A of ratan interposed between other layers B O of felt or other suitable material, the foot being provided with an upper play-recess b, cord apertures c d, pin-apertures e f g, and

ankle-joint'bushing h customary in artificial feet of ordinary construction. The toe portion'ofthe ratan layer-A of the foot is made thinner than the remainder in order that it may more readily yield'to pressure, the thickness of said layer throughout being proportioned .to the weight of the person for whom said foot is designed. Ratan is a cheap, light, tough, and durable flexible material that can be readily fashioned by ordinary woodworking-tools, and it has been found admirably adapted for my purpose of a yielding stilfenerin an artificiallfoot that is partly felt or other elastic material.

Having thus described my invention, what Patent, is-

An artificial foot comprising layers of elastic material and an interposed layer of ratan constituting a yielding stifiener for the foot.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wiscousin, in the presence of two witnesses.
